• There are 2 programs
  • PART 1 - webserver1.cpp is a Single-threaded web server written in C++.
  • PART 3 - webserver2.cpp is a Multi-threaded web server written in C++.
• The server listens on a specified port 52837, accepts incoming client connections, and serves HTML and PDF files to clients.
• Each client connection is handled in a separate thread in the webserver3.cpp program, allowing the server to handle multiple client requests concurrently.
• The server parses incoming HTTP requests, retrieves requested files, and sends HTTP responses, supporting basic web server functionalities.
• The server supports only "GET" request method and HTML and PDF file type.

• The servers were tested and handles upto 500MB PDF File transfers.
• The service was denied on repeated request to the server for large PDF Files (500MB).
• Multithreading is implemented with pthread to support all versions of C++. "thread" is compatible only after C++ 11
• The servers were tested with 10MB, 50MB, 100MB and 500MB PDF File size.
• The servers were tested through client requests in the same network.
• If the client denies the response (cancels PDF download) the server raises error and is terminated.
• Can switch to "DEBUG" mode to analyse the program flow. (to switch set const bool DEBUG = true;)

I have done this assignment completely on my own. I have not copied it, nor have I given my solution to anyone else. I understand that if I am involved in plagiarism or cheating I will have to sign an official form that I have cheated and that this form will be stored in my official university record. I also understand that I will receive a grade of "0" for the involved assignment and my grade will be reduced by one level (e.g., from "A" to "A-" or from "B+" to "B") for my first offense, and that I will receive a grade of "F" for the course for any additional offense of any kind.
